Mt William Creek flows recommence

Jan 30, 2019, 00:00 AM
Flows recommence for Mt William Creek today. The small volumes are intended to refill refuge pools and improve water quality in the creek itself.

Flows Cease over Christmas/New Year's Break

Dec 19, 2018, 00:00 AM
Flows are ceasing over the Christmas/New Year's Break across the system and will be recommencing for the Wimmera and MacKenzie Rivers and Burnt Creek early in 2019 with Mt William Creek flows starting later in January.

Low flows for Wimmera River

Nov 13, 2018, 00:00 AM
After several days of higher flows from Lake Lonsdale they are being reduced to provide flows for the Mt William Creek and Wimmera River. They will reduce further later in November when flows will recommence from Taylors Lake.

Flows for Burnt and Mt William Creek

Oct 17, 2018, 00:00 AM
Given the dry conditions, low flows have commenced for the Burnt Creek and lower Mt William Creek.

Flows recommence

Sep 14, 2018, 00:00 AM
Environmental flows for the MacKenzie River at Distribution Heads will recommence on Monday 17th September. A week later flows will recommence for the Wimmera River from Taylors Lake. They will continue to mid-October.

Conditions postpone releases

Aug 27, 2018, 00:00 AM
Small flows from local runoff as well as a need to retain water for future environmental flows given the very dry conditions mean that environmental flows are postponed until at least early spring.

Regulated releases temporarily ceasing

Jul 1, 2018, 00:00 AM
Due to dry conditions in 2017, more limited allocations of environmental water will mean that flows across systems will be interspersed with periods of no flow. Flows are planned to recommence later in July.

Taylor's Lake Flows Recommencing

May 9, 2018, 00:00 AM
Flows for the Wimmera River from Taylor's Lake are planned to recommence today following the repairs to the Outlet Channel.

Taylors Lake Releases Cease

Apr 18, 2018, 00:00 AM
Urgent repair works require flows for the Wimmera River from Taylors Lake to cease today. Flows for the MacKenzie River, Burnt and Mt William Creeks are continuing.
